Are my tyres safe?

Even though they are stored in a dark garage.

Those are the same bags that I bought in 2017. I use them and they are excellent.

Ah well, for that price I'd be daft not to! Thanks.

I've emailed Bridgestone and asked for their opinion. They should know!

I find all the Heyner stuff excellent!

There's your problem.
Store them in bags and they last much much longer, as they don't dry out

That's what's counter-intuitive to me...they would be fine on the car but not off it. I think I get why but it's not something that's occurred to me before now.

Ordered!

Are new tyres stored in bags up until they are first fitted? According to KwikFit "Tyres are considered to be ‘new’ and are suitable for retail sale for, up to 5 years from the original date of production"... some interesting info in this link https://www.kwik-fit.com/tyres/information/tyre-age

They're Bridgestone Turanza and have done perhaps 5000 miles and were new last May. Are they even safe? I'm guessing not.

They've been stored in my workshop which is basically a dry former stable. They were stored on their side stacked in two piles of two.

Any advice gratefully received.

This is a new trend I have noticed in the last 3 years ..on tyres just a couple of years old, I would see what advice the manufacturer will give , what is the date code by the way ?
There is something in the pipeline about the MOT test checking the age of the tyres I could never advise keep on using them like that .... and neither should you take such advice...

Uniroyal's take/advice

Storing tyres at home
It may too cost-prohibitive or simply too inconvenient to store them away from your home so, if you are going to try and do it yourself, the next question is how and where to store tyres so that they stay in peak condition?

The most important thing to avoid is cracking on the tyre wall. This happens when tyres are left unused for a long period of time. When tyres are in motion, anti-UV oxidisation chemicals keep the tyres flexible. However, when they’re static, these chemicals are not distributed evenly and dry patches appear.

You therefore need to minimise exposure to UV while your tyres are in storage. Once you’ve cleaned them – using a mild soapy detergent – and left them to air dry, use a tyre marker to mark their original location (left front, right rear etc.). Then wrap each tyre in an opaque black bag. You can buy tyre protection bags from motoring retailers or use black refuse bags. Try to extract as much air as possible before sealing them.

Store your tyres off the ground, ideally on a tyre rack, in a cool, dry, clean environment. Keep the tyres away from any heating or hot water supplies.

If your tyres are still connected to their wheels you can store your tyres horizontally on top of each other, sidewall to sidewall. If the tyres are being stored without tyres, align them vertically, with their sidewalls touching. Remember, to give the oxidisation chemicals the opportunity to reach the entire circumference of the tyre, you should rotate the tyres regularly, a bit at a time.

Even if you’ve stored your tyres carefully, they may still dry up through lack of use. Before refitting them to your car, look carefully for any cracks. If in doubt, ask your local Uniroyal dealer to check them over for you.

Thanks everyone - date code Jan 19 so should be fine and the side walls are absolutely fine so I might be worrying about nothing...let's see what Bridgestone say.

Good point made earlier about new tyres not being stored in bags but perhaps they have some sort of stuff painted on them which wears off once exposed to the road.

I'm getting a new car in July anyway so these only have to last between being refitted and then...safely of course!

Really good thread. New tyres are stored on racks, upright in a aired, and clear type room.

Also, whilst it is indeed correct they can be sold for some time every set I have ever ordered have been a few weeks old only.
